We only have backup activity at night at this time, all to diskpool, so
I backup my diskpool to copypool every morning prior to migration for
efficiency (like you say). So, can you take it a little further? How
would I track just active versions beyond that? Eventually the offsite
tapes would contain (as they do now) a mix of active and inactive
versions, with no way of expiring inactive versions on copypool only.
I realize that a lot of installations require a copy of the entire
storage pool to ensure recovery from media failure, but not all sites
find that insurance worth the price of the tapes. I think I have
expressed this to this list before, so I won't bore you with my whining
about this again. But if there is an easy, viable way to achieve this
with ADSM, I would like to hear it.
